Currently: Methods rather than Methodologies
Excellence-based approach Gradual approach

Limits of Excellence-based Approaches
Certification is effective, but it is not sufficient
100% conformance on everything,
really better than 100% conformance on
what is useful?
We must not discard certification,We must make it smarter
WCAGAre the efforts worth the results?

Limits of current Gradual Approaches
The constraints of the project definehow requirements are handled
Measuring conformance: What does 75%
conformance mean?
We need gradual implementation phases consistent with users needs
WCAG levels arenot structuring
anymore
Users needs are deprioritized

The Basis of MIPAW
How to choose what to start with,while addressing users’ most urgent needs?
![Page 6: Mipaw: Model for a Progressive Implementation of Web Accessibility - Web4All](https://reader035.fdocuments.in/reader035/viewer/2022062705/556ba5f2d8b42a207e8b4a47/html5/thumbnails/6.jpg)

The very Primary Need…
Access to information?
Can WCAG be structured with this angle?

A Preliminary Survey
• 8 experts• Accessiweb checklist
Workgroup
• To study the notion of « Access to information » related to user impact
Goal
• Classification of each criterion on 2 axes:• Does it prevent access to information for some users? (yes/no)• If not, assess user impact (strong/weak)
Method

Findings of this Preliminary Survey
Criteria A AA AAA Total
Critical for access to information 35 3 7 45
Non-critical, with strong impact 33 10 1688
Non-critical, with weak or null impact 14 7 8
• Access to information is a structuring notion• All 3 WCAG levels are represented in each set• A first set of criteria considered as critical for access to information, can
be defined. Covers all 3 levels.

Another result appearedA secondary classification, based on these indicators: presence, relevance, and strength of user impact (significant or null with regards to access to information)

Inception of MIPAW
The Model for a Progressive Implementation is based on this distribution
Principle: to distribute the criteria on an arbitrary scale, structured by the notion of « access to information »
Access to information
Essential Device UX Improvement

MIPAW and WCAG Conformance
Compatibility with WCAG levels and conformance100% WCAG conformance on each level is reached when criteria are met in the 4 groups, for the considered WCAG level.
In this model, the threshold « Access to information » is considered as the pivotal point to identify essential users needs.

Outlooks for MIPAW
Some of our expectations regarding this Model for a Progressive Implementation of Web Accessibility:
• To be representative of a possible gradual implementation strategy• less demanding than purely excellence-based approaches• yet with no compromises with regards to essential users needs.
• Likely to provide an adequate support for project management methodologies with gradual implementation phases, while remaining focused on users needs.
• Theoretical playground for couplings between WCAG, excellence-based approaches, and gradual strategies.
• Can support measurement systems that include defect-tolerance
